Understanding Uptake of NPK
I am working on a bit of a project here.
If we look at uptake of macro nutrients throughout the week. Lets say we express uptake as percentage of dosage. For example: If I dose 100ppm of N in my aquarium and at the end of the week my reading is 70ppm, then we can say that we have 30% uptake.
How does this percentage vary from macro to macro? Are you finding that you have a certain percentage of uptake across NPK, or are you finding that each nutrient has a different percentage?
What is your current uptake percentage in your tank?
The goal of this is to categorize uptake into 3 categories: Low, Medium, High. To accomplish this, please include your percent of uptake and your tank setup.
The outcome of this will be great for all of us when I am finished with my project.
